    Each supervisor 44 is configured to perform the supervision of the routing module 36 associated with it, in particular to perform one or more of the following actions relating to said routing module 36: startup, configuration management, updating, monitoring and fault management.
    Thus, the avionic computer 14 according to the invention makes it possible to reduce the number of equipment on board the aircraft 10 by integrating the routing module 36, whereas, in the state of the art, the latter is usually included in a dedicated network switch.
    In the example of FIG. 1, all the network switches 24 are implemented by routing modules 36 integrated in respective avionic computers 14, which makes it possible to dispense with four dedicated network switches.
    The communication network 20 according to the invention then has a reduced mass and volume, as well as a lower power consumption, by reducing the number of devices forming the communication network 20.
    This also reduces the maintenance costs of the aircraft 10.
    The communication network 20 according to the invention also makes it possible to improve the wiring inside the aircraft 10, in particular to limit the number of external data links 16, some data links now being internal to the avionics computer 14, as previously described with the internal connection 42 between the transmission / reception module 40 and the routing module 36 when these two modules 36, 40 are arranged inside a single and single protective housing 26.
    In addition optional, the fact that the routing module 36 is deactivable further improves the scalability of the communication network 20, a single avionics computer 14 can then operate either as a network switch or a computer not dedicated to network, as two at a time.
    It is thus conceivable that the avionic computer 14 according to the invention makes it possible to simplify the communication within the aircraft 10.
